Sustained energy output of an endothermic animal and an ectothermic animal as a function of core temperature This image shows the difference between endotherms and ectotherms. The mouse is endothermic and regulates its body temperature through homeostasis.
Endotherms cannot, in general, afford such long periods without food, but suitably adapted ectotherms can wait without expending much energy. Endothermic vertebrate species are therefore less dependent on the environmental conditions and have developed a higher variability (both within and between species) in their daily patterns of activity.
In general, warm-bloodedness refers to three separate categories of thermoregulation.. Endothermy [a] is the ability of some creatures to control their body temperatures through internal means such as muscle shivering or increasing their metabolism.
In biology, thermoregulation is the ability of an organism to maintain its body temperature, and the term "endotherm" refers to an organism that can do so from "within" by using the heat released by its internal bodily functions (vs. an "ectotherm", which relies on external, environmental heat sources) to maintain an adequate temperature. [14]
Heterothermy or heterothermia (from Greek ἕτερος heteros "other" and θέρμη thermē "heat") is a physiological term for animals that vary between self-regulating their body temperature, and allowing the surrounding environment to affect it.

Kleptothermy is observed, particularly amongst juveniles, in endotherms such as bats [36] and birds (such as the mousebird [37] and emperor penguin [38]). This allows the individuals to increase their thermal inertia (as with gigantothermy) and so reduce heat loss. [39] Some ectotherms share burrows of ectotherms. Other animals exploit termite ...
